绿色电脑主板俯视特写

正方形俯拍特写，一块深绿色印刷电路板占满画面，板面密布细密铜色走线与浅色焊点。左上方为黑色方形CPU散热风扇，四角有十字螺丝，中央贴有紫黑色圆形标签，标签带白色与蓝色文字。风扇周围及下方分布多枚黑色矩形集成电路芯片，部分芯片印有白色“H-113”等字样，下部可见多组平行排列的芯片和一枚印有“15V G1K”的方形芯片。右侧有两根竖直长条形黑色内存插槽，下方边缘有横向长插槽与密集金属针脚，板面散布圆柱形电容、电阻和小型贴片元件。写实产品摄影风格，顶视机位，无背景，均匀柔和照明，绿色为主色调，金属与黑色元件对比清晰，画幅比例1:1。

Square top-down close-up product photograph of a dark green printed circuit board filling the frame, densely covered with fine copper traces and pale solder points. In the upper left is a black square CPU cooling fan with four Phillips-head corner screws and a circular purple-and-white center sticker with text. Around and below the fan are multiple black rectangular integrated circuit chips, some marked with white labels such as H-113, plus a square chip labeled 15V G1K in the lower area. Two long vertical black RAM slots run along the right side, with a horizontal expansion slot and dense metal pins near the bottom edge. Scattered cylindrical capacitors, resistors, and small surface-mount components sit across the board. Realistic product photography, overhead view, no background, even soft lighting, green dominant color palette, crisp contrast between black components and metal elements, 1:1 aspect ratio.
